BACKGROUND OF THE INVENTION

The present invention pertains to grill brushes for cleaning grill grates such as the grates of gas fired barbecue grills and a cleaning system employing a grate and grill brush specially configured for use therewith.

The use of brushes and scrapers for the cleaning of grill grates of gas grills is well known. Typically, grill brushes have a head portion and a handle portion. Grill brushes known in the art typically have metallic bristles which are generally all of a constant length and form a generally planar abrasive surface. This bristle configuration permits the top surface of the grill to be scrubbed with the grill brush but does not facilitate the cleaning of the sides of the grill grate bars. With known grill brushes it is therefore difficult to remove accumulated deposits from the sides of the grate bars without significant effort.

It would therefore be desirable to have a grill brush that more effectively removes deposits and grease from the sides of the grate bars of a grill grate while also removing deposits from the top surface of the grate.

BRIEF SUMMARY OF THE INVENTION

In accordance with the present invention an improved grill brush is disclosed. The brush has a head portion and a handle portion. Metallic bristles are mounted in and extend from a surface of the head portion. In one embodiment the bristles are arranged in generally parallel rows that extend from a surface of the head portion by first and second heights, wherein the second height is less than the first height. When the bristles of the grill brush are urged against the grill grate for the purpose of cleaning the grate, the longer bristles extend into the openings between parallel spaced grill grate bars and scrub the sides of the grate bars while the shorter bristles scrub the top surface of the bars of the grill grate. The width of the rows of narrow bristles may be selected to correspond generally to the width of the grill grate bar with which the grill brush is intended to be used. Similarly, the width of the rows of longer bristles may be specified to correspond to the spacing between the grill grate bars. The specific width of the rows of the shorter bristles and the longer bristles may be specified to provide effective cleaning of different grill grate designs.

In another embodiment of the invention, the contour of the top surface of the bristles is specified to correspond to the contour formed by the grate to promote effective scrubbing and removal of deposits from the top surface and accessible side surfaces of the grate.

Other features and advantages of the presently disclosed grill brush and grill cleaning system will be apparent to those of ordinary skill in the art from the Detailed Description of the Invention that follows.

DETAILED DESCRIPTION OF THE INVENTION

In accordance with the present invention an improved grill brush and a grill brush cleaning system is disclosed. The presently disclosed grill brush and cleaning system provides for more effective removal of deposits and grease that accumulate during use on the grates of grills, such as gas barbecue grills.

A prior art grill brush is depicted schematically in FIGS. 1 a and 1 b. Referring to FIGS. 1 a and 1 b, the grill brush 10 includes a head portion 12 a handle portion 14 and a plurality of metallic bristles 16 mounted to the head portion 12. The handle portion 14 may be include a thermoplastic or rubber covering (not shown) for added comfort. In one embodiment, the handle portion 14 is angled between 120-160 degrees with respect to the head portion 12. As illustrated in FIGS. 1 a and 1 b, the metallic bristles 16 are of a generally constant length and the ends of the bristles lie form a cleaning surface that is generally planar. Known prior art grill brushes typically are fabricated of wood or plastic.

Referring to FIGS. 2 a and 2 b, an grill brush in accordance with the present invention is shown. The grill brush 20 includes a head portion 22, a handle portion 24 and metallic bristles 26 that are mounted within the head portion and extend from the bottom surface thereof. As illustrated in FIG. 2 b, the metallic bristles 26 are arranged in generally parallel rows of having first and second different heights. More specifically, the metallic bristles 26 include longer bristles 26 a which are intended to extend between the spaces formed between adjacent parallel grate bars and shorter bristles 26 b which are intended to scrape and clean the top surface of the grill grate.

Grill grates are provided in various forms. One conventional grill grate 30 includes generally circular rods 32 maintained in position by welded cross members 34 as illustrated in FIG. 3 a. Additionally, another conventional grill grate 40 has grate bars 42 formed with a generally planar top surface 44 and angled side surfaces 46. The grate bars 40 are maintained in position by welded cross members 48.

The use of the presently disclosed grill brush for the cleaning of grill grates is illustrated in FIGS. 4 a and 4 b. More specifically, the grill brush 20 is positioned over the circular rods 32 such that the rods 30 are urged into the recesses formed between the rows of different height and bristles 26. The bristles 26 of the grill brush 20 may then be urged against the circular rods 32 while the grill brush is moved back-and-forth along the length of the circular rods to clean the rods 32 and remove deposits therefrom. The shorter bristles 26 b are formed in generally parallel rows of a specified width W1 and deform to provide scrubbing or the curved upper surface of the circular rods 32. The longer bristles 26 a are provided in rows of width W2 and are generally parallel to the other rows of bristles. The longer bristels 26 a extend between the openings formed by the parallel circular rods 32 located generally on spaced centerlines C1 so as to provide more effective scrubbing of the sides of the rods 32 than is readily achieved using conventional grill brushes. It should be appreciated that the disclosed brush may be used with grill grates having centerlines corresponding to the centerlines between shorter bristel 26 b rows or with grates having different centerline spacings.

Similarly, referring to FIG. 4 b, the presently disclosed grill brush 20 may be employed to effectively clean a grill grate of a type depicted in FIG. 3 b with grates spaced on centerlines C2. Referring to FIG. 4 b, the grill brush 20 is disposed over the grate bars 42 with the rows of longer bristles 26 a having a width W4 such that the longer bristles deform and extending into the openings formed between the grate bars 42. The shorter bristels 26 b are arranged in rows of width W3 so as to provide effective cleaning of the top surface of the grate bars 42. It will be appreciated that the bristles 26 will deform when urged against the grate bars 42. As indicated above, the bristles 26 of the grill brush 20 may be urged against the grate bars while the grill brush 20 is moved back-and-forth along at least a portion of the length of the grate bars 42 to clean the grate bars 42 and remove deposits therefrom.

In an improved cleaning system, the grill brush and the grate are especially adapted for use with one another. More specifically, referring to FIGS. 4 a and 4 b, the narrow rows or narrow bristles 26 b may be spaced on centerlines that correspond to the centerlines of the circular rods 32 or the grate bars 42 and may have a width specified so as to generally conform to the top surface of the respective grate. In the case of the circular rods 32 the width of the narrow bristle rows may be slightly less than the diameter of the circular rods 32 so that cleaning of the rods 32 will be achieved with deformation of the bristles 26 when urged into contact with the rods 32. Similarly, referring to FIG. 4 b, the width of the narrow rows of bristles 26 b may be specified so as to generally correspond to the width of the top surface 44 of the grate bars 42. The width of rows of the longer bristles 26 a specified to generally correspond to the width of the spacing between the top surfaces 44 of the grate bars 42. The longer bristles 26 a will thus deform when urged into the openings between the grate bars 42 and effectively scrape deposits from the sides 46 of the respective grate bars 42.

In another embodiment of the invention illustrated in FIG. 5, the contour of the bristles in cross-section is specified to generally correspond to the contour of the cross-section of the grate to be cleaned. More specifically, referring to FIG. 5 a cross-section of a grill brush 50 is shown positioned above a grate of the type depicted in FIG. 3 b. The grill brush 50 includes a head portion 52 with bristles 54 mounted in and extending from the head portion 52. The bristles 54 have a contour that generally corresponds to the cross-section of the grate contour so that the bristles 54 conform to the grate contour when urged into contact therewith to provide effective scrubbing of the top and side surfaces of the grate bars.

The bristles in the grill brushes herein described may be fabricated of a metallic material such as brass or stainless steel. Given that grill brushes are often used outdoors, it is preferable that the bristles be fabricated of a material that will not rust such as brass or stainless steel. While the illustrated embodiment is described in terms of the use of metallic bristles, it should be appreciated that any bristles that are suitably stiff and resilient may be employed, including non-metallic bristles.

The body of the grill brush may be fabricated as an integral structure of wood or plastic or any other suitable material. Alternatively, the handle may be fabricated separately from the head portion of the grill brush and may be mounted thereto.

The bristles may be mounted in a head portion 60 of a grill brush in preformed recesses 62 depicted in FIG. 6, or alternatively, the bristles may be secured within a molded head portion via an insert molding process. More specifically, in one known process used for the mounting of bristles in grill brushes, U-shaped bristles 70 are passed through an eye member 72 (see FIG. 7) and the eye member 72 is forced into a preformed recess 62 within the head portion 60 to securely retain the bristles within the head portion 62 as a plurality of tufts of bristles. The lengths of the U-shaped bristles in the presently disclosed invention are specified so as to provide the desired non-planar contour of the bristle surface to achieve effective cleaning of a grill grate. Thus, the bristles depicted schmematically in FIGS. 2, 4 and 5 may comprise tufts of bristles that have end which provide a surface having the above-described grill cleaning profiles. Additionally, while FIG. 7 depicts an eye member 72 that is used to secure the u-shaped bristles within the recesses 62 of the head portion 60, the u-shaped bristles may be secured within the head portion 60 with any curved or straight retaining member which is sized to be press fit into a recess 62 after insertion of the u-shaped bristles to captively retain the bristles within the head portion 60. The retaining member may be metallic or any other suitable material.

As illustrated in FIG. 8, a head portion 80 may include an additional support member 82 having an abrasive pad 84 mounted thereto. Moreover, the head portion 80 of a grill brush in accordance with the present invention may have a metallic scraper 86 mounted to the front of the head portion 80 opposite the handle 78 to permit more aggressive scraping of deposits on the surfaces of a grill grate. It should be appreciated that an abrasive pad 84 and a scraper 86 may be included with any of the embodiments herein disclosed.

Though the handle 78 is shown in FIG. 8 as extending from the head portion 80 in the illustrated embodiments, it should be appreciated that the grill brush may be fabricated such that the handle 78 extends from or is coupled to the abrasive pad supporting member 82 or the supporting structure between the head portion 80 and the abrasive pad supporting member 82. In one embodiment, the handle 78 position is configured so as to form an angle between a plane passing generally through the ends of the bristles and a line passing generally longitudinally through the handle and additionally, to form an angle between a plane passing generally through the exposed surface of the abrasive pad and the line passing generally longitudinally through the handle to facilitate ease of use of the grill brush when employing either the bristles or the abrasive pad for grill cleaning.

It will further be apparent to those of ordinary skill in the art that that variations of and modifications to the above described grill brush and grill cleaning system may be made without departing from the inventive concepts disclosed herein. Accordingly, the invention should not be viewed as limited except by the scope and spirit of the appended claims.
